The function that relates the sales and the number of muffins is :
S = 2.5 m
The sales amount can be find by the total sales. That is , if there are n products to sell and selling amount is x rs. then we can easily find the total sales by multiplying them and by this total sales we can easily find the number of items sold per units and vice versa.
In the question given,
amount (A) = $ 250.00
Now take any of two values from table ,
Choose any two points and calculate the slope:
slope = [tex]\frac{50 - 20}{20 - 8}[/tex] = 2.5
thus, y = 2.5x
Hence we can say the the function that relates the sales and the number of muffins is :
S = 2.5 m
where, S = sales amount
m = number of muffins to be sell
